Please note: if you have an 03 VoIP line number then unfortunately SMS replies cannot be routed back as 03 numbers are not SMS enabled.  

Although you can use an 03 number to send out the SMS from it cannot be used for SMS replies. 

The same applies to a company name, if this is used in the SMS origination - replies to the SMS cannot be routed back if a company name has been added.  

For SMS replies to be received back, the SMS origination number must either be a geographic VoIP line number such as 01 or a virtual mobile number.
